Yup.

This is actually why I am skeptical of the entire idea of buying a replacement pack aside from cost.@DaveInOly likes to say that packs are a JIT production item but is that really true, and even if true in the past, will it be true here on out ?

Only the new owners of the battery plant know for sure.

Made no such claim. Cells are produced in batches that takes SEVERAL weeks to complete before the assembly process can begin. This is the likely reason for the "4-8 week" delivery window for pack replacements where we see anywhere from a few days to 2 months. It all depends on where the next batch is in the process.

Cells will be using the most recent chemistry but are still different in build, layering, etc. than current cells by default.

+/- a couple of weeks is JIT so far as I am concerned.

So, same question: how do you know the cells are only (up to) a few weeks old ?

Since I have made no such claim, I don't know. Again; cells are processed in batches eventually being part of whatever size pack they see fit to build. Due to some 3 day turnarounds on pack replacements, they are obviously NOT built to order.

So this means some packs will be fresh off the assembly line and some won't. How old will they be? who knows but doubting they would be much over a few months if that and with proper storage, the time wouldn't be a factor anyway.

But we are primarily talking about cells in a highly controlled environment. I will check around but seems to me I remember being told that cells can sit for 2 years or so without "any" degradation in storage. So what stops Nissan from creating big batches? Well, its like any other long term tool. Why put XXX away and possibly risk not using some of it when you could put away X and have the high likelihood of using all of it?

Just a thought --I'm still unsure why Nissan jacked up the price of the replacement pack but perhaps shelf life is the answer:

A warranty replacement can supply a pack with some shelf life degradation and be adequate for customer satisfaction but it would be (rightly) criticized if sold as a replacement pack. So perhaps bought replacement packs really are "one off" items that would be more expensive now that Nissan has moved on to other packs and other vendors.

This general notion that replacement packs are going to be good value has always been suspect in my mind and I think Nissan has just provided the first proof of my skepticism. Nissan can change its motto to:

"Pay a little less now, and a lot more later."

This is not a business strategy, but a side-effect of using tech with poor battery longevity.

Just leads to third party options in the long run, if I had the knowledge, resources and finances I would open an EV battery business. Pricing is key but if you can offer longer range, faster charing etc etc they would fly off the shelves. Now I understand that if it's not a Nissan offering one could cause warranty issues so ideally one would replace after that has expired and they are faced with a battery replacement.
